' ELECTRIC I'SAD-IRGN.

To all whom, it may concern Be it known that I, HARRY RosnN'rnAL,

' a citizen of the UnitedStates, residing at Camden, in the county ofCamden and State 0t New Jersey, have invented certain newand usefulImprovements in Electric Sad- Irons, of which the following is aspecifica- .tion..

The object of my invention is" to provide a novel, simple-and eiiicient,electrically heated sad iron in which currents of air, heated by. a}resistance coil ma y be employed to t ansi er the heat to difl'erentparts of the iron and particularly to the point end thereof.

- tures of construction hereinafter fully deof the bodv. 45-

scribed and particularly claimed.

In the accompanying drawings, illustrating my invention, Figure 1, is aside elevation of my improved sad iron. Fig. 2, is a longitudinal.vertical section thereof. Fig.

3, is a horizontal section, on line 33of Fig. .2. Fig. l, is atransverse section, on

'line of Fig. 2.

' Referring to the drawings, 5 designates the body of the iron and (3 ahandle suitably secured toithe top of the bodv The bod portion 5 isinadehollow, as shown, and is provided with openings 7 in the upper portionsof its sides to permit air to pass into and from the body 5 for apurposehereinafter explained.

Located within the hollow bodv 5 is a. block 8 comprising a horizontalportion 9, extending well into the hollow bodv and a vertical endportion .10 which is fitted to and closes an opening .11 in the rear endwall The. block 3 is held in place by a suitable set screw 12, screwedinto and through the top of the body 5 and engaging the top of the endportion 10 of the. block.

The horizontal portion '9 of the block 3 is made hollo its top beingclosed bv a ton wall 12-3. its sides being closed by side walls '14 andits rear end being closedby the portion 10. lea ving the block open atits bottom and at its forward end. as sho n.

the block 8 is a resistance coil 15 which is The rear end of the. core16 provided with projections 17 which are inserted into openings in therear wall of the block 8; and. the body of the core lo is provided witha removable pin 18 which extendshorizontally through the core and intoopenings in the side walls 1% of the block 8. Thus the core 16 issupported within the block 8 by the pin 18 and the projections 17. Byremoving the pin 18 the projections 17 may be readily withdrawn fromtheir openings in the block 9 and the core 16 and its coil 15 removedfrom the block.

The ends of the coil 15 are connected to suitable binding posts 15) ontheend portion 10 of the block 9, and connected to the binding posts 19are lead wires .ZOwhich extend through an openin 21 in the end portion10 to the exterior of the iron and form con tinuations of the ends ofthe coil 15, the wires '21 being adapted to be connected to any suitablesource of supply of electric current.

When electric current is supplied to the coil. 15, the heat therefromheats the air within the hollow body portion 5 and causes the air tocirculate therein through various courses and to flow into and from thebody portion 5 through the openings 7 therein. Some of the air thusheated passes from within the hollow portion 9 of the block around thebottoms of the side walls l-t thereof and up between the same and theside walls of the'bod-y 5 of the iron, but most of the moving air passesfrom the hollow portion 9 out through the open end, in the direction ofthe arrow in Fig. 2, and thereby maintains the point end of the iron ata higher temperature than the remaining portions of the iron. The hotair circulating within the body portion 5 quickly heats all partsthereof and distributes the heat over the top portion thereof as well asheating the bottom portion so that if the bottom portion be suddenlychilled, it will quickly recover heat from the heat contained in the topor upper portions thereof.

I claim:

1. In an electric sad iron. a hollow body portion having air inletand-outlet openings therein, and a block provided with a resistance coiland supported within the bodyportion in spaced felation to the interiorwalls thereof, said bloek covering the top and exposing the bottom ofsaid coil.

' -2.' In an electric sad iron, a hollow body 'portion having air inletand outlet openings therein, a hollow block supported within the bodyportion in spaced relation to the interior walls thereof and having aresistance Icoil supported therein, said block having-a closed top,closed sides, a closed rear end, an

open bottom and an opening in, its'forward.
